what does history tell us? >> i think there is some concern about donor fatigue for a couple of reasons. one because the economy is, you know, weaker than it has been at other times. on the other hand, we saw disaster relief giving for haiti turn out to be quite strong. quite sustained for many months. so that doesn't tell the whole story. i mean i think that's part of it. in fact, perhaps some of the haiti relief giving is part of the donor fatigue. on the other hand, i think that general when americans give, the average gift has ranged between $125 and $135 per household for different disasters. so the gifts tend to be relatively small. a lot of people giving a relatively small amount. in fact the gift for all the disasters we've track has been $are 50. you know that most people can spend $50 in a lot of different ways so it's not as if people are refinancing their house in order to give these disaster relief gifts. that's not to disparage those gifts. it's just to say that they're relatively small amounts. f
